A new data set called the South African Financial Diaries has been produced, based on a sample of 166 households, drawn from three different areas in South Africa – Langa, Lugangeni and Diepsloot. The selected households represent a range of dwelling types and wealth categories. A unique methodology was used to create a year-long daily data set of every income, expense and financial transaction used by every one of these households. Within this sample, households used, on average, 17 different financial instruments over the course of the study year. A composite household portfolio, based on all 166 households, would have an average of four savings instruments, two insurance instruments and 11 credit instruments. The same composite household portfolio would have about 30 per cent formal instruments and 70 per cent informal instruments. Interestingly, it was found that rural households use as many financial instruments as urban ones.
